Networking in C++

Networking is a crucial aspect of algorithmic trading in C++. It involves communication between different software components or systems over a network. In this screen, we will explore various networking concepts in C++, including APIs and HTTP.

APIs in C++

Application Programming Interfaces (APIs) allow programs to communicate with external systems or services. APIs provide a set of functions and protocols that define how different software components can interact with each other. In the context of algorithmic trading, APIs are often used to retrieve market data, place orders, and manage trading strategies.

Here's a simple example of how you can make an API request in C++ using the curl library:

1#include <iostream>
2#include <curl/curl.h>
3
4int main() {
5  CURL *curl;
6  CURLcode res;
7
8  curl_global_init(CURL_GLOBAL_DEFAULT);
9
10  curl = curl_easy_init();
11  if (curl) {
12    curl_easy_setopt(curl, CURLOPT_URL, "https://api.example.com/endpoint");
13    res = curl_easy_perform(curl);
14
15    if (res != CURLE_OK)
16      fprintf(stderr, "curl_easy_perform() failed: %s\n", curl_easy_strerror(res));
17
18    curl_easy_cleanup(curl);
19  }
20
21  curl_global_cleanup();
22
23  return 0;
24}
